Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a paper guide device for a printer used as a computer terminal or the like.

Configuration of Conventional Example and Its Problems The paper guide device in a conventional printer will be described below with reference to FIGS. 1 and 2. In the figure,
Reference numeral 1 denotes a platen, which is attached to a printer chassis 3 by platen shafts 2 attached to both end surfaces. A printing head 4 slides in the longitudinal direction of the platen 1 and prints by coming into contact with the printing paper 5 wound around the platen 1. Reference numeral 6 denotes a tractor, which is fixed to the printer chassis 3 by shafts 7 and 8 fixed through the interior thereof, and is equipped with an annular belt inside. Projections are formed at regular intervals on the surface of the belt. A portion of the belt is exposed above the tractor 6, and the belt is driven by a drive device provided inside the tractor 6,
The exposed portion of the protrusion fits into a guide hole (not shown) provided at the end of the printing paper 5, and the printing paper 5 is sent to the rear of the printer. Reference numeral 9 denotes a paper guide, through which the shafts 7 and 8 pass loosely, and is adapted to move along the shafts 7 and 8. Reference numeral 10 denotes a paper partition member made of wire or the like, and both ends of the paper partition member 10 are fixed to the printer chassis 3.

Next, its operation will be explained. The printing paper 5 fed from below the paper partition member 10 is guided in the circumferential direction of the platen 1, and is guided through the protrusion on the belt exposed at the upper part of the tractor 6 and the guide hole provided at the end of the printing paper 5. are fitted together, and as the belt is driven, they are sequentially sent out to the rear of the printer. The sent-out printing paper 5 slides on the upper surface of the paper partition member 10 and is sent further backward. During the above operation, the paper guide 9 supports the center portion of the printing paper 5 and prevents the printing paper 5 from loosening.

However, in the above structure, the paper guide 9 is not fixed, and the shaft 7,
The movement was unstable, as it sometimes moved left and right along the line 8. Further, there was a problem in that static electricity generated due to friction between the printing paper 5, the head 4, the paper guide 9, etc. caused malfunction of the printer.

Purpose of the invention The present invention is to solve the above-mentioned conventional problems, and to fix the paper guide with a simple structure, and to quickly eliminate static electricity generated by friction. The purpose of the present invention is to provide a paper guide device for a printer that can perform the following steps.

Structure of the Invention The paper guide device of the invention attaches a paper partition member made of a wire to a part of a paper guide, and presses the paper partition member against a shaft to which the paper guide is movably attached. Accordingly, the paper guide is fixed to a part of the shaft, the paper partition member and the shaft are both made of conductive material, and the shaft is grounded. In this way, the position of the paper guide can be reliably fixed, and static electricity generated by friction can also be quickly removed via the paper partition member and the shaft.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In the figure, reference numeral 11 denotes a paper guide with conductive shafts 7 and 8 loosely inserted through its sides. A notch 12 is provided in a part of the rear surface of the paper guide 11. Reference numeral 13 denotes a paper partition member formed of a conductive wire material, and both ends thereof fit into recesses 11a provided on the side surface of the paper guide 11, and the paper partition member is mounted rotatably in a direction perpendicular to the shafts 7 and 8. It is being A curved portion 13a is formed in a portion of the paper partition member 13, and with the curved portion 13a pressed against the shaft 7, a portion of the wire rod is hung in the notch 12 of the paper guide 11. There is. In this state, the paper guide 11 is securely fixed at any position on the shaft 7.
When the printer is operated in this state, the printing paper 5 fed from below the paper partition member 13 is guided in the circumferential direction of the platen 1, passes over the upper surface of the paper guide 11, and is further guided to the paper partition member 13. and sent to the rear of the printer. In addition, static electricity generated due to friction during paper feeding is removed by the conductive paper partition member 13.
and is transmitted through the shaft 7 and grounded.

By the way, to release the fixation between the paper guide 11 and the shaft 7, move the paper partition member 13 in the direction of arrows A and A.
This can be easily done by spreading the wire against its elasticity and releasing the hook at the notch 12. In this state, the paper guide 11 is slidable along the shafts 7 and 8.

Effects of the invention As described above, according to the invention, the paper partition member can be
The paper guide is pressed against the conductive shaft using its elasticity, and the pressure is used to fix the paper guide in a desired position, so the paper guide does not move during printing, resulting in extremely stable operation. can be set. Further, by grounding the shaft, static electricity generated due to contact between the paper and the paper partition member, etc., is removed through the paper partition member and the shaft. Therefore, printer malfunctions caused by static electricity can be eliminated and stable performance can be maintained.
